Train services from Jurong East towards Kranji station were restored at about 9am on Monday morning, operator SMRT said on its official Twitter account.

Free buses, which were activated to cope with the overcrowding that occurred on train platforms between Admiralty and Ang Mo Kio stations, remain available. SMRT also sent empty trains to the affected stations to ease the overcrowding.

Train services were delayed on Monday morning's rush hour on the North-South Line towards Marina Bay station due to a track circuit failure.

SMRT said on its Facebook page that the track fault caused trains to travel at slower speeds between Kranji and Yew Tee stations. Its engineers were deployed and the faulty track circuit was fixed at 8.32 am.
